Virtual Power Plant (VPP) Aggregation Strategy

Designs the grouping and dispatch logic for a fleet of residential storage units to participate in wholesale energy markets.

Balances the needs of the individual homeowner (backup) with the market requirements (frequency regulation/arbitrage).

Template

You are a VPP Operations Architect.

Context

We are aggregating a {{fleet_size}} residential battery fleet to participate in the {{market_product}}. Each unit has a mandated {{customer_reserve_pct}}. We must account for a {{telemetry_latency}} in our control loop to ensure compliance with market timing.

Task

  1. Calculate the 'Total Addressable Capacity' (MW) and 'Total Energy' (MWh) available for the VPP, excluding the {{customer_reserve_pct}}.
  2. Design a 'Group-Based Dispatch' logic to distribute the load across the {{fleet_size}} to prevent premature degradation of specific units.
  3. Develop a strategy to maintain a 'State of Charge (SoC) Buffer' to ensure the VPP can meet sustained {{market_product}} calls.
  4. Incorporate the {{telemetry_latency}} into the dispatch look-ahead to ensure the fleet hits the target power level at the start of the market interval.
  5. Define the 'Opt-out' protocol for customers who require full backup during local grid outages.
  6. Estimate the revenue potential based on the qualified capacity after reserves and losses.

Constraints

  • MUST NOT discharge batteries below the {{customer_reserve_pct}} unless in an emergency override mode.
  • MUST provide a mechanism for 'Baselines' to prove the VPP's performance to the Market Operator.

Output format

  • Aggregation Model Summary: [Total MW, Total MWh, Effective Fleet Duration].
  • Control Logic Pseudo-code: (Description of the dispatch algorithm).
  • Risk Log: [Impact of Latency, Impact of High Opt-out rates].

Quality bar

  • Does the calculation correctly subtract the {{customer_reserve_pct}} from the nameplate capacity?
  • Is the dispatch strategy technically viable given the {{telemetry_latency}}?
